Give him time, Lily. Let him work on himself. Addiction is a difficult hurdle to clear. If he is serious about recovery, he'll do it whether you are in the picture or not. If he chooses to do the work and keeps at it steadily for a year, then if it is meant for the two of you to be together, God may bring him back to you. A year is a good place to start--to see what your boyfriend is going to do. Whether he is sincere or not. Otherwise, he may go to the sober house for a few weeks and then insist all is better, you let him come back to you, and then he easily could slip back to his old ways. Give him time, because with time you will have a better idea if he is going to beat his addiction or not. Less than a year is just not enough time. And you've already given one man eight years of your life and he never beat his addiction.
